Description
The Tiny LDD Laser Diode Driver is an electronic device that contains stabilized current source (up to 10A) for laser diode (LD) and two controllers for Peltier thermoelectric coolers (TECs). Compact and highly-efficient design limits power dissipation and simplifies heat-sinking requirements. Perfectly suited for single-emitter laser diodes delivering up to 10W of optical power. The Laser Diode Driver incorporates LD protection features like slow current ramp-up (soft start function), current limit, temperature limit and overheating protection.
Features
- Easy controlled
- Soft start function
- User selectable: 2 unidirectional TEC controllers or single bidirectional TEC controller
- Smooth temperature stabilization. Adjustable parameters to avoid temperature oscillations
- Overheating protection for laser diode, crystal and driver
- Can be used in multistage laser systems. Master LDD can start/stop slave LDD’s (from firmaware 1.4 ver.)
- Compact size
- LD current modulation (optional)
- Microprocessor controlled
- USB 2.0 compatible
- Compatible for connecting second power supply (for using driver on full power, second power supply is sold seperatly, please write to sales@wophotonics.com )
- 1 year full service warranty
